Because regulatory bodies demand it? Being employed in a medical school
you are certainly aware that regulatory bodies are very much into eliciting
a "benefit" in terms of "rate of subjects cured" and do not believe in
a treatment effect expressed as a "mere" shift in the parameter.
(Not that this notion weren't my pet peeve; but it's there and we have to
deal with it.)
